Description
Technical field
The present invention relates to the Aluminum Electrolysis Production apparatus field, is an a kind of stubborn spanner that is applicable to the more changing anode device of multifunctional electrolytic machine group specifically.
Background technology
The multifunctional electrolytic machine group is the key equipment on the Aluminum Electrolysis Production line, and automation degree of equipment is high, mainly can accomplish crust breaking, changes anode, feeds in raw material, goes out aluminium, lifts anode electrolytic cell bus, groove overhaul and accomplish other fragmentary handling work.Unit mainly by cart, tool car, go out aluminium dolly, screw air compressor, hydraulic pressure, pneumatic system, 2X8 ton electric hoist and form.Be mounted with more changing anode device, crust breaker, cutting agency on the tool car.More changing anode device, crust breaker are dropped to electrolytic cell and are carried out operations by Driven by Hydraulic Cylinder during work, are recovered to upper limit to mechanism during process finishing.
Twist a key part and be the more important tool of changing anode device, be used to screw and unclamp the capsule anchor clamps.With reference to shown in Figure 1, these parts are driven by hydraulic motor 1 spends strong sliding bush apparatus (guide cylinder 2, splined shaft 3) through shaft coupling 4 transferring power.Hydraulic cylinder 5 (elevating mechanism) drives and twists the capsule anchor clamps place that a spanner 6 drops to anode rod during change poles; Locating rack 7 is held solid back with the contraposition of capsule anchor clamps end axle and is twisted the screw mandrel square toes place that head gets into the capsule anchor clamps, and restart hydraulic motor 1 and unclamp the capsule anchor clamps through transmission device this moment.After changing newly extremely, the hydraulic motor 1 counter-rotating capsule anchor clamps of screwing.
An existing stubborn spanner structure and sealing means are that the inner-rotary type gland of plain type adds the dust ring design; With reference to shown in Figure 2; The upper shed and the lower opening of twisting the stubborn headstock hole of headstock 10 are equipped with gland 11 and dust ring 12; The endoporus of said dust ring 12 tightly is enclosed within on the boss of gland 11, with gland 11 rotations.With reference to shown in Figure 3, there is radial clearance B between the cylindrical of dust ring 12 and the stubborn headstock hole, between gland 11 and the stubborn headstock 10 end play A is arranged, dust gets into through slit A and slit B just.Because having amounts of dust when reinforced, alumina reservoir is scattered; And twist a spanner just below it; Make dust at the upper surface bulk deposition of twisting headstock 10; Along with stubborn 13 rotation, gland 11, dust ring 12 also and then rotate, and constantly A, B get into stubborn headstock 10 inside to so a large amount of dust from the slit.Though bearing 14 is for the band dust cap, still gapped existence between dust ring 12 and the Internal and external cycle, the time gets into manyly once long, finally causes lubricating grease on the bearing 14 to go bad, harden and ineffective, initiation bearing 14 stuck faults.In addition; Because gland 11 is not taked any seal approach with stubborn 13; Therefore dust also maybe from twist 13 install get into the groove of stop tongue of floor clips 15 gland 11 with twist a gap of 13 and and then get into and twist in the headstock 10, cause bearing 14 stuck faults.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, technical problem to be solved by this invention provides a spanner of twisting of a kind of good sealing effect, anti-dust.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of spanner of twisting; Comprise and twist head, stubborn headstock and locating rack, an end of said stubborn headstock is fixedly connected with elevating mechanism, and the other end is fixedly connected with said locating rack; Offer between the two ends and twist the headstock hole; Said stubborn head is rotatably installed in the said stubborn headstock hole, also comprises dust cap, backbone sealing ring and O shape circle
Said dust cap comprise cover plate and by the cover plate edge to the flange that extends below; The middle part of said cover plate is provided with through hole and reaches by the through hole edge to the boss that extends below; The inboard of said boss is provided with groove; Said dust cap is fixed on the upper shed that said stubborn headstock hole was gone up and covered in to said stubborn head through said through hole socket, and the upper surface of said stubborn headstock is protruded in the upper shed in said stubborn headstock hole;
Said backbone sealing ring is fixedly mounted in the said dust cap, and the flange inner of its outer diametric plane and dust cap fits tightly, and its sealing lip is connected with the upper shed socket in said stubborn headstock hole;
Said O shape circle is placed in the groove of offering said boss inboard and sealing shroud is connected on the said stubborn head.
Wherein, the lower opening in said stubborn headstock hole also is installed with backbone sealing ring, and the hole wall in the outer diametric plane of said backbone sealing ring and stubborn headstock hole fits tightly, and the sealing lip of said backbone sealing ring and said stubborn headgear connect in succession.
Wherein, the lower opening in said stubborn headstock hole also is installed with circlip for hole, and said circlip for hole is positioned at the below of the backbone sealing ring that the lower opening in said stubborn headstock hole is provided with.
A spanner of twisting of the present invention is different from prior art, has the following advantages:
1, the cover plate edge of dust cap is provided with flange to extending below; Said flange covers in the upper shed of twisting the headstock hole in the side; Making dust (especially twisting the dust of the upper surface bulk deposition of headstock) to get into from the side of dust cap twists in the headstock hole; And the distance that can only get into dust cap from the bottom up from the bottom of dust cap and laterally move to the thickness of few upper shed greater than said stubborn headstock hole just possibly get into and twists in the headstock hole; Thereby improved the sealing and the anti-dust effect of twisting a spanner greatly, effectively reduced bearing fault, made it under the environment of extremely many dirt, also can work normally;
2, be installed with backbone sealing ring in the dust cap; All has good sealing effectiveness between said backbone sealing ring and dust cap and the stubborn head; Further completely cut off the approach of dust from the bottom entering dust cap of dust cap; Twist in the headstock hole thereby better avoid dust to get into, improved the sealing and the anti-dust effect of twisting a spanner, effectively reduce bearing fault;
3, sealing is provided with O shape circle between the boss of dust cap and stubborn head; Between said O shape circle and stubborn head is static seal; Thereby prevent that dust from getting in the stubborn headstock from twist a groove of the stop tongue that floor clip is installed, improved the sealing and the anti-dust effect of twisting a spanner, effectively reduce bearing fault;
In sum, a spanner of twisting of the present invention has good sealing property and dustproof effect, can be under the environment of extremely many dirt operate as normal and be difficult for breaking down.
